下文将根据该联合接线盒使用状态的不同，分三种情况进行描述。为了使附图连线清晰，附图中的连线仅仅绘出三相电压中的A相。The following description will be divided into three situations according to the different usage states of the combined junction box. In order to make the wiring in the drawing clear, the wiring in the drawing only draws phase A in the three-phase voltage.
(1)当三相三线联合接线盒处于正常工作状态时，第一可调电流联板、第二可调电流联板、第三可调电流联板均处于初始位置。(1) When the three-phase three-wire combined junction box is in a normal working state, the first adjustable current connection board, the second adjustable current connection board, and the third adjustable current connection board are all in the initial position.
如图1所示，当第一可调电流联板5、第二可调电流联板6、第三可调电流联板7均处于初始位置时，基于上述连接关系，三相三线电能表3能够对终端4的用电量进行计量。As shown in Figure 1, when the first adjustable current connecting plate 5, the second adjustable current connecting plate 6, and the third adjustable current connecting plate 7 are all in the initial position, based on the above connection relationship, the three-phase three-wire electric energy meter 3 The power consumption of the terminal 4 can be measured.
(2)当三相三线联合接线盒处于第一短接工作状态时，第一可调电流联板5、第三可调电流联板7均处于初始位置，第二可调电流联板6处于连通第三通道23和第四通道24的位置。从图2的信号流向箭头中可以看出，三相三线电能表3和终端4均被连入电路中不存在二者被短接的情况。(2) When the three-phase three-wire combined junction box is in the first short-circuit working state, the first adjustable current connecting plate 5 and the third adjustable current connecting plate 7 are in the initial position, and the second adjustable current connecting plate 6 is in the initial position. It communicates with the position of the third channel 23 and the fourth channel 24 . It can be seen from the signal flow arrows in Fig. 2 that the three-phase three-wire electric energy meter 3 and the terminal 4 are both connected into the circuit and there is no short circuit between them.
如图2所示，需要对终端4进行短接时，在前一种情况的基础上，将第二可调电流联板6向右侧移动，即从初始位置中连通第二通道22和第三通道23的位置，改为连通第三通道和第四通道的位置，这样从图3中的信号流向箭头可以看出，通过第二可调电流联板6的移动，使得终端4中没有电流的流动，实现了将终端短接的效果。As shown in Figure 2, when the terminal 4 needs to be short-circuited, on the basis of the previous situation, the second adjustable current connecting plate 6 is moved to the right, that is, the second channel 22 and the second channel 22 are connected from the initial position. The position of the three channels 23 is changed to the position connecting the third channel and the fourth channel, so that it can be seen from the signal flow arrows in Fig. 3 that the movement of the second adjustable current connecting plate 6 causes no current in the terminal 4 The flow realizes the effect of short-circuiting the terminals.
(3)当三相三线联合接线盒处于第二短接工作状态时，第三可调电流联板7处于初始位置，第一可调电流联板5处于连通第一通道21和第二通道22的位置，第二可调电流联板6处于连通第三通道23和第四通道24的位置。(3) When the three-phase three-wire combined junction box is in the second short-circuit working state, the third adjustable current connecting plate 7 is in the initial position, and the first adjustable current connecting plate 5 is in the connection between the first channel 21 and the second channel 22 position, the second adjustable current connecting plate 6 is in a position communicating with the third channel 23 and the fourth channel 24 .
如图3所示，需要对三相三线电能表3和终端4同时进行短接时，在前一种情况的基础上，再将第一可调电流联板5向左移动，即从初始位置连通第二通道23和第三通道23的位置，改为连通第一通道和第二通道的位置，此时，第二可调电流联板6依然处于连通第三通道23和第四通道24的位置，这样从图4中的信号流向箭头可以看出，通过第一可调电流联板5、第二可调电流联板6的移动，使得三相三线电能表3和终端4中没有电流的流动，实现了将终端短接的效果。As shown in Figure 3, when it is necessary to short-circuit the three-phase three-wire electric energy meter 3 and the terminal 4 at the same time, on the basis of the previous situation, the first adjustable current connecting plate 5 is moved to the left, that is, from the initial position Connect the position of the second passage 23 and the third passage 23 to the position of connecting the first passage and the second passage. At this time, the second adjustable current connecting plate 6 is still in the position of connecting the third passage 23 and the fourth passage 24. In this way, it can be seen from the signal flow arrows in Figure 4 that through the movement of the first adjustable current connecting plate 5 and the second adjustable current connecting plate 6, there is no current in the three-phase three-wire electric energy meter 3 and the terminal 4 The flow realizes the effect of short-circuiting the terminals.
基于前文提出的能够根据工作状态将可调电流联板进行位置移动的三相三线联合接线盒，如图4所示，该接线盒的使用方法为：Based on the three-phase three-wire combined junction box proposed above that can move the adjustable current connection board according to the working state, as shown in Figure 4, the usage method of the junction box is as follows:
41、当三相三线联合接线盒处于正常工作状态时，将第一可调电流联板、第二可调电流联板以及第三可调电流联板移动至初始位置。41. When the three-phase three-wire combined junction box is in a normal working state, move the first adjustable current connecting board, the second adjustable current connecting board and the third adjustable current connecting board to the initial position.
42、当三相三线联合接线盒处于短接终端的工作状态时，将第二可调电流联板右移，处于连通第三通道和第四通道的位置，第一可调电流联板、第三可调电流联板的位置保持在初始位置处。42. When the three-phase three-wire combined junction box is in the working state of short-circuiting the terminal, move the second adjustable current connecting plate to the right, and it is in the position connecting the third channel and the fourth channel. The first adjustable current connecting plate, the second The position of the three adjustable current coupling plates remains at the initial position.
43、当三相三线联合接线盒处于同时短接三相三线电能表和终端的工作状态时，将第一可调电流联板左移，处于连通第一通道和第二通道的位置，第二可调电流联板右移，处于连通第三通道和第四通道的位置，第三可调电流联板保持在初始位置处。43. When the three-phase three-wire combined junction box is in the working state of short-circuiting the three-phase three-wire electric energy meter and the terminal at the same time, move the first adjustable current connecting plate to the left to be in the position connecting the first channel and the second channel, and the second The adjustable current connecting plate moves to the right to be in the position connecting the third channel and the fourth channel, and the third adjustable current connecting plate remains at the initial position.
